Problematic fired 6944 kg steam coal boiler (1) Henan small boiler gas boiler should be noted, by the Henan coal into gas boiler, i.e. the original becomes a negative pressure is now slightly positive pressure combustion burner, the furnace must be noted that the structure and the sealing wall problem; (2) prevent explosion of the furnace, a gas fired boiler furnace to Henan, when defective or incomplete combustion of fuel atomization gas in the furnace or heating surface of the end aggregate, fire or explosion occurs, and therefore, in appropriate sites shall boiler explosion vent means, while the control program should be added to the ignition and flame protection device of automatic control, to ensure safe operation of the boiler; (3) the selection and arrangement of the burner close to the furnace in the form of, should the flame in the furnace better fullness without forming dead air; adjacent flame of the burner to avoid mutual interference; low load flame holding in the furnace central position, offset from the center of the furnace to avoid the flame center of symmetry; unburned gas-air mixture is not in contact with the heated surface , to avoid the formation of incomplete combustion gases; hot flame to avoid high-speed heating surface erosion, in order to avoid excessive heating surface so that the wall strength of overheating. Burner arrangement also consider the gas pipe and duct arrangement, easy to operate, inspection and maintenance; (4) Mechanized layered coal-fired boiler, gas boiler to change Henan, first removing its longitudinal arch, taking into account the increase in the bottom heating surface to replace the grate, grate to prevent overheating burn; (5) gas velocity Henan convection heating surface is not limited by the gas boiler ash abrasion conditions, gas velocity can be increased properly, so the convection heat transfer heating surface coefficient increases, without increasing the heating surface of the boiler, can increase the pressure of the boiler, steam-water separation capability should be noted that at this time means the pot to ensure the quality of steam, hot air for the boiler had particularly important.
The whole structure of normal pressure BoilerThe whole structure of atmospheric pressure 6944 kg steam coal boiler consists of boiler body and auxiliary equipment. The main components of boiler, such as furnace, boiler barrel, burner, water-cooled wall superheater, economizer, air preheater, frame and furnace wall, constitute the core part of steam production, which is called boiler body. The two main components of the boiler body are the furnace and the drum. The furnace, also known as the combustion chamber, is the space for fuel combustion. The furnace in which the solid fuel is placed on the grate is called a layer furnace, also known as a bed furnace; the liquid, gas or powdered solid fuel is injected into the furnace burning in the fire chamber, which is called a chamber furnace, or a fire chamber furnace; the air turns coal particles into the furnace, which is called a chamber furnace, or a fire chamber furnace; the air turns the coal particles into a chamber furnace, also known as a fire chamber furnace. It is called boiling furnace, also called fluidization bed furnace, in which the furnace with boiling state and suitable for burning inferior fuel is called boiling furnace, and the cylindrical furnace which uses air flow to make coal particles rotate at high speed and burns intensively is called whirlwind furnace. The furnace design needs to take fully into account the characteristics of the fuel used. Each boiler should burn the original fuel as far as possible. The economy and reliability of boiler operation may be reduced when the fuel with different characteristics is used.
You must know the problems of energy consumption 6944 kg steam coal boiler (boiler thermal efficiency) 1, because the thermal efficiency of boiler problems of a high exhaust gas temperature. b sootblowers into low. c ash combustible large. d is too large or too small boiler oxygen. e heat loss is large. f large air preheater air leakage rate. g coarse pulverized coal. h steam - water quality is poor. I defective equipment, operating parameters are forced down. 2, measures to solve the problem of a lower exhaust gas temperature. b timely elimination of soot blowers defects and improve the investment rate of soot blowers. c reduce fuel ash, slag combustibles. d control the amount of oxygen in the boiler. e reduce heat loss. f air preheater to reduce air leakage rate. g qualified coal fineness control. h to improve the quality of soft drinks. i According to circumstances, the boiler heating surface adjustment arrangement.
